Annie has recently implemented a video surveillance system for her organization. What is the largest driver for new ongoing costs for an unmonitored video surveillance system?

Video surveillance system storage can drive additional costs based on decisions like how long video is retained, sensitivity levels, video resolution, and how heavily trafficked camera covered areas are. Licensing may grow if additional cameras are added, but there is no information in the question indicating changes in the size of the implementation. Since this is an unmonitored system, no guards are involved, and camera maintenance is not a typical issue for a newly deployed system.
